well if your are going to open a Store you would need a number of hardcore followers that support the store and play there regularly and participate in your promotions and campaigns

And also a larger number of players who support your shop but don't play there. a.e - me I don't really play at Alvins but I support his store even if I can buy cheaper online. so all my stuff come from there and before that games castle.

maybe rather than a store why not try build a hobby group and supply them with the hobby products and slowly build your group base

I used to work for GW. I was asked to go on the management training course but didn't in the end. I also think the cost of the hobby is horrifically high!! There is not the same level of income between east and west Malaysia. I may look for alternative sources of the models to help bring the hobby to those less well off.Simon
